I worked at said retailer as well, as a matter of fact I was in charge of said millions of customer reviews. And you know what? BDB's were mostly used just because of distribution. They were pushed to all live servers nightly, that way you had no dependency on one giant server.
This eventually changed as everything moved to a service architecture, and those BDBs were also eventually stuck in an Oracle database as well.
Basically BDB's, although great for some things were more a product of how to scale initially, and the pain quickly became so big they moved away from them on most things.
So I wouldn't consider said retailers experience as a terribly pro-nosql one.
